The Vaporfly 4 is the lightest model yet, using new athlete insights and Nike’s unparalleled standard of precise design to level up the silhouette that started the super shoe revolution eight years ago, furthering Nike’s position at the leading edge of racing innovation. Built for all runners and inspired by the best athletes, the new Vaporfly is the most versatile Nike racing model on the market, setting the standard for distances ranging from the 5K to the marathon. The silhouette blends the stability of the Vaporfly 3 and the softness of its veritable predecessor, introducing a finely tuned balance of support and propulsion that serves runners of all abilities and intensities. That propulsion is born from an updated Nike Flyplate curvature, which helps unlock leverage from the foot and ankle, as well as the energy return generated by ZoomX foam, Nike’s lightest and most resilient midsole compound. It’s also boosted by the silhouette’s featherweight design, which is roughly 10% lighter than the Vaporfly 3 and 20 grams lighter than the original Vaporfly (2017). The latest model’s midsole design saves weight by eliminating foam where it isn’t needed, while a new upper increases comfort and fit consistency while contributing to the overall weight savings of the shoe.
